' My invention relatesto safety razors and more particularly has reference' to the combination with safety razor mountings of magnetic reconditioning means for the razor It is known thata razor blade does not present 'a uniform cutting edge when examined under the microscope but that the edge consists of a multiplicity of very small and fine teeth which are very sensitiveand readily distorted. It has heretofore been proposed to recondition' the. edges of the blade: by" contact with a ma et' the fine metallic particles of the blade beingt'h'ereby re-al'igned in accordance with the magnetic lines of force andth'e' cuttin edge thereby rendered more e'fiici'ent'. "owever, treatment of razor blades in 'thiszmann'er' has necessitated the removal of the blade'from thevv razor mountingi'orjliol'der and has required the use of azmagnetic conditioning device apart from the razor mounting.

It is accordingly an object of my invention to provide in a razor mounting a magnetic device so positioned as to recondition' one of the cutting edges of a double edge blade while the other edge is exposed for use.-

A more specific object of my invention resides in the provision of a razor mounting 2550 adapted to hold two or more double edge blades and so constructed as to magnetically recondition certain of the cutting edges while at least two cutting edges are exposed for use.

Other objects and advantages of my invention will appear from the more detailed description thereof. v

I have found that, in order to properly recondition a razor blade magnetically, it is essential that the magnet be positioned direct- 1y under the cutting edge for otherwise the magnetic lines of-force pull the fine metal particles in all directions and do not properly align the microscopic teeth of the cutting edge. Accordingly, in the construction of my improved razor mounting,the magnet is disposed directly under the edge of the blade which is not exposed for use.

For a more detailed understanding of my invention reference will be had to the accompanying drawings in which I 1 isan end "View of a razor mounting containing two separate blades;

Base plate 1 1 has a longitudinal s-l'ot centrall'y thereof tosnugly receive the enlarged upper end' 12 of the magnetic'hand'le which presents ma 'neticsurface for contact with a the-blades To'p p-l-ate li'i of the razor niou'nt- (0 ing is provided with the usual proj ectionsj or lugs 1 12$ extending through corresponding openings in base plate 11 as shown. A.: stem I5 ,'which rnay be either cylindrical or rectangular',as= shown, i' sfixed to OTiHtGgI'al with R5 top plate 1'3and extendsthrough slot 16in handle- 1 0mm l owe'r end'of"stem= 15 being provided "with threaded projection I7 adapted toreceive nut 18 for holding the completeassembly' togethery Razor blade's 1'9fand 20, provided with suitable perforationsfor' slots 21 to fit between lugs-I45, are supported between the topand bottom p'l'ates 'ori opposite sides of the razor mounting: By" reason of the construction 86 illustrated; it wi ll' beseen th at the inner cutting edges 22 of the blades rest upon; and are disposed directlyover magnetic surface- 12 whi'l'ethe'opposite cutting edges 23 are exposed for use. j o f From the foregoing it will be apparent that my razor mounting at all times presents two cutting'edges exposed for use while two other cutting edges are being" simultaneously subjected to'rnag'neti'c reconditioning by contact with magnetic surface 12, the magnet being disposed directly under the cutting edges to give a higher degree of reconditioning than is obtainable by otherwise positioning the k, bledewith respect to tlre magnet, asabov'e explained. When cutting edges 23 have become dull by use, the position of the blades is reversed to expose edges 22 for use and to subject edges 23 to magnetic treatment by contact with magnet 12, such reversal being repeated indefinitely.

It will therefore be seen that I have devised a razor mounting adapted to alternately recondition the opposite edges of a blade or blades while retained in the mounting and without requiring the use of additional appa ratus apart from the razor.

Although I have shown and described a preferred embodiment of my device, the invention is not to be construed as limited thereto as various changes and modifications may be made therein without departing from the spirit and scope of my invention. For example, the handle 10 need not necessarily constitute the magnet, it being only essential that the temporarily unused cutting edges be directly exposed to magnetic action. Also the invention is not limited to the use of two blades as the device will be operative and useful with only one blade and with only slight modification the mounting may be made to hold three or more blades. Accordingly, the invention is to be construed as limited only by the scope of the appended claims.

Having described my invention, I claim:

1. A razor mounting comprising a bottom guard plate, a magnet disposed centrally of said plate, a top plate, and means for retaining a pair of razor blades between said plates with one blade on each side of and overlapping said magnet. v 2. A safety razor comprising top and bot tom guard plates, a magnet separable from said top and bottom plates disposed centrally of said plates, and a pair of razor blades each having two cutting edges retained between said plates on opposite sides of said magnet, saidmagnet being in contact with the inner edge of each of said blades.

3. A razor mounting comprising top and thereof exposed for use and the other edge disposed over said aperture, and a magnet supported in said aperture directly beneath said other edge of the blade, said aperture and magnet being of a length at least substantially equal to that of the blade.

6. A safety razor comprising top and bot tom guard plates, an elongated aperture centrally of said bottom plate, a double edge razor blade retained between said plates on each side of said aperture with one edge of each blade exposed for use and the other edge thereof disposed over said aperture, and a magnet supported in said aperture directly beneath said other edge of each blade, said aperture and magnet being of a length at least substantially equal to that of the blades.

7. A razor mounting comprising top and bottom guard plates, an elongated aperture in said bottom plate, a magnet disposed in said aperture, and means for retaining a double edge razor blade between said plates with one edge thereof exposed for use and the other edge thereof directly over said magnet.

8. A razor mounting comprising top and bottom guard plates, an elongated aperture centrally of said bottom plate, a magnet disposed in said aperture, and means for retaining a pair of double edge razor blades between said plates with one blade on each side of said aperture and with one edge of each blade exposed for use and the other edge of each blade directly over said magnet.

In testimony whereof, I affix my signature.
